The VRN Patent Authority
Page

This page is believed to comprise the Internet's most comprehensive list
of patent authorities on the web. If you know of any patent, trademark or
intellectual property authority missing, please don't hesitate to contact
me. I try my best to keep the list updated, but things change rapidly in
cyberspace. By the way: I have been thinking of rating the official patent
authority sites regarding their user-friendliness and content. Any comments
to that end is also welcome.
